Neuronal subserving of behavior before and after chronic ethanol treatment.

We have previously shown that an acute ethanol dose (1 g/kg), sufficient to impair the performance of a healthy rabbit, also reversibly depresses the activity of those limbic-cortex neurons that are specifically activated during recently learned behavioral acts. Our new morphological and neurophysiological data suggest a death of such neurons after 9-month chronic ethanol treatment. The effect of acute ethanol administration on neurons and performance speed in alcoholic rabbits was opposite to that found in healthy animals. Our results help to understand why neurocognition of alcoholics changes and why acute low-level alcohol ingestion influences them differently than healthy individuals.

Formation and realization of individual experience.

This article describes the methodological approach of systemic psychophysiology. In the framework of this approach a wide range of experimental data is analyzed: results of neuronal recordings in vitro and in awake normal and pathological animals learning to perform and performing both complex instrumental and simple behavioral acts. Another block of analyzed data is based on experiments with human subjects who learn and perform the tasks of categorization of words and operator tasks, participate in group game activity, and answer the questionnaires of psychodiagnostic methods. As a result of this analysis, the systemic psychophysiology approach is used to describe qualitatively and quantitatively the formation and realization of individual experience.

[Individual-typologic features of EEG structure].

EEG monopolarly recorded in points F3, F4, O1, O2 of 20 healthy subjects in six states (quiet wakefulness with open or closed eyes, spontaneous button pressings in arbitrary moments of time, listening to clicks, reaction to clicks by pressing the button at random or at equal intervals between stimuli), were processed by means of the computer program transforming the raw EEG tracings to a sequence of stationary segments. The accumulated segments were divided into classes of "similar" ones by a two-stage procedure of cluster analysis. In each lead six types of segments were identified forming populations of structural units of an individual human EEG. Four types were recorded all over the brain: their spectra were of a great resemblance in different brain areas. The EEG of each individual was characterized by a certain combination of segment types which practically did not change by their quality in different states of the subject.

[Patterns in the shaping and realization of individual experience].

This article describes the methodological approach of systemic psychology. In the framework of this approach a wide range of experimental data is analyzed: results of neuronal recordings in vitro and in awake normal and pathological animals learning to perform and performing both complex instrumental and simple behavioral acts. Another block of analyzed data is based on the experiments with human subjects that learn and perform the tasks of categorization of words and operator tasks, subjects, performing group game activity and answering the questionnaires of psychodiagnostic methods. As a result of this analysis, the system psychology approach is used to describe qualitatively and quantitatively the formation and realization of individual experience.
